What customers say

Customer reviews

  • New toilet fitted — pain-free experience

    “Max was extremely kind and flexible — the first toilet was too big so he came back an hour later with a smaller one and stayed into the evening to fit it. Also heat-dried the floor and resealed a small leak. Highly recommended!”

  • Checkatrade

    Helped when others weren't interested!

    “Very happy with the response, service and work carried out at very short notice by this team — where no one else on Checkatrade could be bothered!”

    Stuart U

  • Fast, transparent emergency drainage repair

    “Amir Qome and Mohsen arrived within 20 minutes. They texted updates, sent photos/videos of every important step, put in temporary safety measures and completed a fragile, complex job in 4.5 hours — at a lower price than previous invoices. I’ll only use this company from now on.”

    Ellie Castano

  • Brilliant boiler service from start to finish

    “Arrived on time, very respectful and professional, worked quickly, and left everything clean and tidy after fixing the boiler. Really appreciated how efficient and hassle-free the whole job was. Would definitely recommend.”

    “Initially changed our pump for our water pressure (advised from a previous plumber), but that didn't solve our problem. Diako at Ninja Plumbers sorted out the issue the next week for a very reasonable price! Our water pressure now works perfectly!”

    “Ali was amazing! Has made my bathroom feel like a luxury hotel! He was so considerate of me and my son it was a pleasure to have him working in my house! His attention to detail is one of many reasons I’d have him back working in my place, thank you Ali 🙏”

What we clear

Inside the house and out to the manhole

Slow sinks, a toilet that will not clear, or a drain backing up in the garden — cleared with the right equipment.

  • Blocked toilets

    Cleared properly, not pushed further down

  • Slow sinks, baths and showers

    Traps, wastes and shared branches

  • External drains and gullies

    Manholes, yard gullies and soil stacks

  • High-pressure jetting

    For fat, scale and compacted blockages

  • CCTV drain surveys

    When the cause is not obvious

  • Recurring blockages

    Roots and collapsed sections traced

Before we arrive

Stop flushing, and skip the caustic cleaner

Every flush into a blocked pan adds water that cannot drain, and is how a blockage becomes a flood. Caustic cleaner rarely clears a real blockage, damages older pipework, and means an engineer is reaching into a trap full of it.

  • Stop flushing

    Every flush into a blocked pan adds water that cannot drain, and is how a blockage becomes a flood. If the level is dropping slowly it is partial and can usually wait for a normal appointment.

  • Please skip the caustic cleaner

    It rarely clears a real blockage, damages older pipework, and means an engineer is reaching into a trap full of caustic liquid. If you have already used some, tell us when you call.

  • If it keeps happening, we find out why

    Roots, fat, or a collapsed section. Clearing the same drain repeatedly costs more over a year than surveying it once.

How it works

No mystery, no surprise invoice

  1. Tell us what is blocked

    Which fixture, whether it is draining slowly or not at all, and whether anything has already been poured down it.

  2. We agree the price first

    You get a price before work starts. If the blockage turns out to be a collapsed drain rather than a clog, we stop and tell you.

  3. Cleared, and the cause explained

    We clear it, show you what caused it, and tell you honestly whether it will come back.

Questions

Can you come today?

Usually. Call the booking line, describe what is happening, and we will tell you honestly when we can be there.

Is the drain my responsibility?

Broadly, pipework inside your boundary is yours and the shared sewer beyond it is Thames Water’s. We will tell you which it is rather than charge you for their problem.

Do you work on blocks of flats?

Yes, including shared soil stacks and communal drainage for managing agents.
